In the UK, Lloyd’s Register and LucidCatalyst released a study on November 26 examining how small modular reactors could be deployed aboard large container vessels to replace conventional marine fuel. Commissioned by Seaspan Corporation, the report models a 15,000 TEU Neo Panamax ship operating entirely on nuclear power over multi-year intervals without relying on bunkering infrastructure.
The analysis estimates that a comparable conventionally fueled ship spends around $50 million per year on bunker fuel and another $18 million on carbon penalties. A nuclear vessel would not incur those costs, offering an entirely different operating model rather than incremental savings.
At a cruising speed of 25 knots, the nuclear vessel could complete more round voyages annually. The removal of fuel tanks and auxiliary systems also frees up cargo space, resulting in up to 38 percent higher throughput compared to traditional designs.
The report argues that with sufficient industry commitment, nuclear propulsion could be commercially viable within four years. Lloyd’s Register is leading work on safety and regulatory frameworks, while LucidCatalyst emphasizes the need for a coordinated supply chain and procurement strategy to bring production costs within reach of commercial shipping operators.
